Only an independent observer would be able to judge nature, for example God. In this poem the independent power is the witch who cooks her soup of nature, she knows what ingredients she needs to add.The writer describes this situation by putting the persons into a natural environment. On one side there was no shade and there weren't any trees, he says.

I was excited to stay.
